STE Ali-ENGINE.

To all whom it mag concern:

Be it known that I, Winonnrr KnrcowsKI, an Austrian subject, and resident of Chicopee Falls, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Steam-Engines, of which the following is a -full, clear, and exact description.

- plicity, high operative efhciency for the atgine shaft.

tainment of a balanced or steady running and for'practicability of the assemblage oi the. arts making up the complete engine.

T e invention consists in thecombinations and arrangements of parts and the constructions of certain of the parts, all substantiall as hereinafter fully described and set fort 1n the claims.

The improved engine constructed with I double steam chambers or cylinders and is, tons respectively provided therein, is i ustrated in the accompanying drawings in which,

Figure 1 isavertical sectionalview through the engine on the plane of the axis of the on Fig. 2 is a vertical sectional view at right angles to Fig. 1. I Line 2*2, on Fig. 1 indicates the plane on which Fig. 2 1s taken, and line 11, on Fig. 2, indicates the plane of sectionof the first view. Fig. 3 is a.

perspective view of the double 0 posed pistons and the intermediate coup ng constituting in substance a portion of the engine shaft. n

Similar characters or rererenoe indicate corres' onding parts in all of the views.

In t e drawlngs,-A represents the on no body constructed, in the present exemgli 50 cation, with double pressure chambers B of annular form arranged in separated parallel planes-and concentrically outside of. a central shaft opening C which extends entirely, transversely through the engine body. Spaces a of circular or annular form, form communication between the annular pres- Specifioation of Letters Patent.

sure chambers and the shaft opening which is concentrically1 inside thereof, and at the upper side of t e engine body the same is constructed with double chamber enlargements 1) b, in which are hinged, at their upper edgewise portions, the abutment gates D, said gates being individually mounted on short shafts gi, towhich they are rigidly afiixed and which have hearings in, and are prtfijected to the exterior of the engine body.

F represent steam conduits leading into 1 the pressure chamber enlargements, both being connected with a steam chestG,with which steam supply ipe H has connection, and in which steam chest is adouble ported.

rotary cut-off valve J carried on a shaft K provided with acra'nk arm e to which the rod' f of an eccentric strap f is connected, said eccentric strap embracing the eccentric) on the engine shaft L, which shaft is dis osed within, and extended endwise beyon the aforementioned shaft opening,

The valve openings or ports in the cut oil valve for the respective pressure chambers are arranged in ofi'set relations so that when one. is opened: the other is closed and vice ,versa,-no particular novelty residing in the double cut oil valve and the means for oper-' ating it.

have exhaust outlets M: in similar relations at oints correspondingly removed from th sai chamber enlargements b, and as particularly shown in Fig. 2. The en ine shaft has opposite radial webs or arms I? I in parallelism and m planes coincident with the central vertical planes of the pressurechambers, the same having their dis osition inthe spaces a which connect the she t opening C with the ressure chambers; hnd said arms carry at t eir-outer ends disk-shaped pistons or win s O which it the walls of the pressure chem are which 1n cross sectional contour are circular.

N arranged inop'position thereon- The engine body is shown as comprising at central section 10 and outer section 12, 12,

these sections having openings or cavities;

therein which when the sections are all matched to other and secured by bolts produce the c ambers and v chamber enlargements of the before described formations and relations The engine shaft is made in three sections viz: an intermediate section 13 and two outer sections 14 and 14, the latter section.

. 35 f Both of the annular pressure chambers being integral with the piston carrying arms N and they have each at the inner side thereof an apertured or clutch forming hub 16 matching into which for ,detachable connection are the lug like ends 17, 17 of the intermediate shaft section 13.

In the assemblage of the parts of the engine the intermediate shaft section 13 is placed in the shaft opening portion comprised within the middle engine body section 10; the shaft sections 14, 14, are then brought to place at op osite sides of the middle section and into c utch like engagement with the said middle section,the. pistons and their arms assuming their proper positions as one therewith; and then the outer engine body sections 12, 12, are brought to place at the opposite sides of the middle section 13, freely s ipping over the stripped outer extremities of the engine shaft sections 14, 14, and the several engine body sections are then securely bolted together.

The gates or abutments D are periodically and alternately operated in their proper times relatively to the cycles of the revoluble pistons by means as follows:

On the end of each -j ournal shaft (Z to which an abutment gate is rigidly afiixed, is a lever arm iconnected with which is a thrust rod j playing through a guide lug 7r on the side'of the engine body, the lower roller provided end. j of the thrust rod having a cooperative impmgementpin the cam m on the adjacent en 0 the engine shaft, 'a retracting s ring 0 between the lug and shoulder on the t rust rod assuring the roper movements of the thrust rod in the direction the reverse of that positively imparted by the cam.

Assumin a given piston is in the position representetf by full lines in Fig. 2, at what ma, be considered the end of its working cyc e or stroke, and when the pressure chamher is, by the position of the piston, open to communication with the exhaust conduit M,

' the cut off valve for the iven cylinder will be momentarily closed; t e piston proceeding in its revoluble course in the direction of the arrow will be permitted to pass the gate or abutment D by the timely upward swinging movement of the latter out of the way, the gate so soon as the piston shall have reached the position intlicated by the dotted lines Fig. 2, having returned to its barrier position, at which time also the port of the cut off valve will be opened for the admission of steam into the pressure chamber. And the piston prevents the steam from passing -inetlectively to *the exhaust conduit, the

piston, of course, being subject to the motive power for the greater portion of its cycle. And it is o be understood that by having the pistons arranged in alternation or radial opposition and the conj unctive mechanism timed for their seasonable actions properly in relation of each other, the engine may be run economically factory steadiness.

I claim 1.
